Companies I've built for

Zuwa took B2B outbound off my plate so I could stay focused on investors and partners. He built the outreach system and CRM integration, ran lead sourcing and drafted replies for my review. He's organized, fast and easy to work with.”

Do you need a CTO yet?

Answer a few quick questions about your company and get a straight answer: yes, not yet, part-time, or full-time. You'll also see the risks I'd look at first, and what I'd leave alone.

It takes about a minute. If you book a call afterward, your answers come with you.

Question 1 of 8

Where's the company today?

Investing in a company instead? Ask about technical diligence (opens Cal.com in a new tab)

Three ways to work together.

Pick the one that fits where you are. If you'd rather start small, begin with the review, and the fee counts toward what comes next. Not sure which fits? The one-minute CTO check suggests one.

  • Fractional CTO

    When the team needs senior leadership

    Senior engineering leadership before you're ready for a full-time hire. I own the architecture, hiring, and delivery, take the technical questions from investors, and build the hardest parts myself.

    • Monthly retainer
    • Scoped to what you need

  • Growth engine

    When you need more customers

    A repeatable way to bring customers in, on whichever channels reach your buyers: email, LinkedIn, calls, partners, or your own product. I build it on existing AI tools where they fit, and custom where they don't.

    • Fixed fee
    • Up and running in about three weeks

  • Execution Risk Review

    Before a decision that's hard to undo

    A fixed-fee look before a raise, a rebuild, or a big architecture call. I review the systems, the team, and the roadmap, then write up what will break, what to fix first, and what to leave alone.

    • From $9,000
    • Takes about two weeks
    How a review works

For investors, I also run technical due diligence on a company before you commit capital, written up for your investment committee. Ask about diligence (opens Cal.com in a new tab)

As we rapidly grew our engineering team, Zuwa helped set the technical bar for who we hired and led some of our mission-critical engineering initiatives. He always gives it his all with focus, offering insight, clarity, and leadership - making everyone around him faster. Plus, he's always a pleasure to work with.”

Zuwa Omigie

I'm Zuwa Omigie.

I've spent 13 years building software and leading engineering teams, most recently as an engineering manager at Coinbase and Shopify.

At Coinbase I led the Canada and Latin America engineering teams: payment rails, compliant onboarding, and the flow of funds in regulated markets. At Shopify I led Shop Pay Installments and the Shop Channel, and before that the team that built the native shopping experience in the Shop app.

I started Migie Labs in 2025 to work with startups directly: leading their engineering, building the hard parts, and setting up the growth engines that bring customers in.

  • You work with me directly, from the first call onward.
  • I take on a small number of engagements at a time.
  • What you share with me stays confidential.
  • Sometimes the right call is to leave a system alone, and I'll say so.

Based in Toronto. LinkedIn

Questions founders ask

Why fractional instead of a full-time CTO?
Most companies need senior judgment on a handful of decisions before they need a full-time executive. Fractional gets you that now, and when it's time to hire, I can help you find and interview the right person.
Why would a CTO build our growth engine?
Finding customers runs on the same things as good engineering: clean data, reliable systems, and measuring what works. A growth engine can use email, LinkedIn, calls, partners, or your own product, and I build it on existing AI tools where they fit and custom where they don't. I ran cold email for BookedWorks before taking on their engineering, and built Theme Health's B2B outbound from scratch.
What does it cost?
Fractional work is a monthly retainer, scoped on a call to what you need. A growth engine is a fixed fee. The Execution Risk Review is a fixed fee too, starting at $9,000.
What kinds of companies do you work with?
Startups building with AI, and companies in payments and commerce, where I spent most of my career. If your problem sits outside what I know, I'll tell you on the first call.
Where are you based?
Toronto. I work in Eastern time with teams across Canada, the US, and Latin America.

Tell me what you're building.

Thirty minutes on a video call. You'll leave knowing where I'd start, and if I'm not the right person for it, I'll tell you.
